' The purpose oit' thel invention 'is to providel a devlce of thekind indicated adapted for use `in connection with water or air may yreadily hand, conveniently `direct the light as desired g to provide a construction in which the' movement of the light is universal'-`that is, movable angul'arly on either a'lvertical or a horizontal axis or both; to provide' vaV construction in which theA -an- Vgu'lar movementsonthe two axes may be.

independently accomplished; tov provide a construction which, when used inconnection .with 'yvehicles,A such as automobiles, maybe conveniently mounted oni thera-diator` and the control Ycarriedby .the steering column "wit-hin "convenientvreach 'of thehand lof the driver; and to providea'structure of simple construction and therefore susceptible of cheap manufacture 'andVv sale.

The bracketA 11 is: in the form of a forwardly extending'y metal bar f integrally vconnected with" which is a depending angular f portion 17 lbored for the' reception ofthe lower'end of thel post, the thrust of the'post'being taken by a'collarflS vbearing upon the upper handedly' or left handedly, depending upon the direction of movement of the post.` The means for .impartingv angular'mo'vement to' pinion `mesl 1es' 'with` ajbevel lgear sector '20 f carried at the 'ifjorward.enitremity of a' tribui .lar shaft 21, the latter passing through a horizontalbearing eye formed in the `vertical wall of the depending angular portion 17 of the bracket. Thetubular shaft, when actuated, obviously imparts' angular movey inent to the sector 2O and this, meshingy with' the pinion 19, will lrotatethelatter. and thus the postwlQ, swinging the lamp angularly and in a direct-ion,corresponding to that in which theshaft 21 is turned.

The pivotalv connection` 15 'between' the 'i and the post provides for the vangular movement'of the former in a vertical lplane and that this 'may be accomplished ata rexfinotevpoint, as from the position of the r"the post comprises a bevel` pinion19'sec'i1red'v tothe shaft and abutting the under facel. of ,the rbody portion-of the bracket .11." This chauleur, the postl is yprovided with'a sleeve 22. l lThis sleevesnuglyl tits' the post but is capable Vof both axial movement 'along the postA and angular movement around `the device.` The sleeve '22 carries an arm 23 having an eyethroiigh whichxthe sleeve passes..l

The sleeve maybe 'eitherixed tothe arm or loosely -lclni'inected4 with ythe latterfsince lrelative movement between the isr not necessary"A to proper. tunctioning but,1f` occurring,

latter, although 'the angular movement is not 1 00' necessary toy thefk proper functioning of the the under edge link 24 which is pivotallyy connected with the arm, as by avpin 25, the remote end of the link being pivotally connected, as at 26, with a clamping collar 27 connected with the stem of the lamp 14. It is apparent that if the sleeve be moved axially of the post, the lamp 14 will, because of the link connection 24, be oscillated on the pivot 15.

Axial movement of the sleeve is effected by means of a shaft 28 extending axially through the hollow shaft 21, this shaft 28 having a crank29 at its forward end formed as a. terminal of a goose neck 30 provided to permit the necessary angular movement of the shaft 28 withoutinterference from klthe post 12. The crank 29 is connected with the sleeve by means of va connecting link 82 having a pivotal connection with the crank pin 33 on the crank 29 and with the pin 64 -on. a guide post 85, the latter being shifted in a verticalplane and it is obvious that this operation may be effected simultaneously with angular movement accomplished. in a horizontal plane by the simultaneous operation ofy the power shaft 21.

The guide post 35 has a bearing in the forward end` of the bracket 11, as indicated at 38, the bracket being slotted from the outer end to provide a clearance space for .the pin 34. The .bracket 11 is preferably supported from the neck 87 of the radiator, a clamp 89 being provided for disposition in. surrounding relation to the neck and connection with the bracket, as by bolts 40. The contraction alone of the clamp upon the vradiatorneck is not relied upon to support the bracket, for the latter is provided with '.a ,segmental plate 41 for abutting engagement with: the under edge of the radiator cap42.

As an additional means of support, a J-bolt 43 is employed and connected with the bracket 11, this J -bolt engaging a hook member 44 connected with the radiator in one of the air openings of the latter. Obviously, any` tendency of the J-bolt to` rock the bracket out of its normalhorizontal position is. met by the segmental plate 41 engaging the filler kcap 42.

`As a vmeans to preclude rattling of the parts and the vibration of the lamp ,on fits vertical axis, the complemental.disks L45 and- 46- are provided,4v the former being secured Yto `the angular-portion 17 ofthe bracket lland the'latter.belngcarriedby thepost 1 2 with respect to which it is axially but not angularly movable. A. compression spring 47 surrounds the lower end of the post and bears upon the lower disk, being compressed between .it andy a .washer 48 carried by the post. The disks 45 and 46 are serrated or toothed on their contacting faces and thus angularmovement of the post is precluded and rattling or vibration with the post as an axis except when sufiicient turning force is imparted to prevent one disk sliding over the other which is possible under such increased. force. due to the fact that the disk 46 is yield-ingly impelled against the disk 45 by the spring 47 .s

The `depending angular portion 17 of the bracket and the forward portions of the shafts 21 and 28, together with the actuating gears and' parts, are enclosed by means of a preferably sheet metal housing 49 secured to the upper or body portion of the bracket 11 by means of screws 50 and the bolts 40 which Secure the clamp 39 to the bracket.

Being mounted centrally of the radiator and at the forward end of the latter and being designed for actuation from the in terior of the vehicle at the drivers seat, it is necessary that the shafts 28 and 21 pass through the radiator and a bearing sleeve 51 is provided for this purpose, this bearing sleeve being threaded at the extremities and receiving the nuts 52 disposed exteriorly and interiorly of the radiator and having gaskets 53 interposed between them and the radiator wall to preclude leaks at the opening made for the reception of the bearing sleeve.

The: shafts 28 and 21 extend to the interior of the vehicle,receivingon theirI extremities respectively the'arms 54 and 55 with which the extremities of the connecting rods 56 and 57 are pivotally connected. These connecting rods at the remote ends have universal connections 58 with the arms 59 and 60 disposed respectively above and below a bearing bracket 61 clamped to the steering column 62.4 The bearing in the bracket 61 supports the lower end o f ra shaft 68 with which the arm 60 vis connected but the arm 59 is connected to the lower end of a tubular shaft 64 surrounding the shaft 63 and in order to preclude rattling of the two shafts,fthe shaft 63 has disposed in surrounding relation to it the compression springs 65 abutting respectively the lower end of the shaft 64 and sideof the arm 59 and the upper side of the arm 60, the springs bearing on` opposite sides of the bearing bracket 61. l

At -the upper end of the steering column a second bracket 66I is provided having a .bearing fory the` shaft 63, this shaft being connected with an actuating lever 67 dis posed on ton vof the bearing while the vshaft 64 ,is connected with a similar lever 68 disposed against the lower face of the bearing. Both levers are provided with spring actuated latches G9 engaging toothed sectors 70, so that angular positions of the arms may be maintained. The levers' 67 and 68 are disposed below but adjacent to the steering Wheel and are, therefore, readily accessible and either one may be actuated separately or both vtogether, and obviously the desired movement of the lamp maybe effectedV by the proper' movement of either or both levers. 1

In the construction shown in Figures 8 and 9, the structure is modified to show the method of use as when the lamp, such as the lamp 14a, is provided with diametrically opposite trunnions. In this construction, the post l2fcarries at the upper end a fork 71,

` the extremities of Whose arms lare pivotally connected 'with the trunnions, as 72. rfhus, the lamp may be moved angularly in a vert-ical plane. In this construction, 'the link 24 is replaced with a bail 73 pivotally connected ywithvthe lamp lon diametrically opposite sides, as indicated at 74, this bail having a pivotal connection with the arm 23 identical with the connection between the link 24 and said arm 23. f
